Thanks, that's a good step forward and it just works.
My github username is cfillion just like here, I'll be glad to push my scripts there.

So the naming convention is "$shortCategory/$author_$shortDescriptionWithoutUnderscores"?EDIT: $author<Underscore> or $author<Space>?

In the meantime I got this to work yesterday: https://i.imgur.com/hkWjsKB.png.
Now I'll figure out how to download a file (to-be script listing) using WDL's http client... (Or I'll just use curl but I'd prefer not to bring any external libraries...)
